The AI Service lets you translate games, or add automated voice-overs capability in real time. Instead of using a ROM patch, this is done by RetroArch taking a screenshot and then sending it to the AI Service listed in your config, which will do OCR (optical character recognition), machine translation, and/or text-to-speech. The service will then return the result and will either be displayed on the screen, or played through the audio output of RetroArch. As is the nature with AI though, accuracy can be an issue. However, machine translation can give a good gist of what’s being said, especially for some language pairs, and text-to-speech can be of great benefit for accessibility.
